STOVE.

SPECIFICATION forming part of Letters Patent No. 313,560, dated March10, 1885.

Application filed February 23, 1884.

To all whom it may concern.-

Be it known that 1, WILLIAM E. WALKER, of Taunton, in the county ofBristol and State of Massachusetts,a citizen of the United States, haveinvented a certain new and useful Improvement in Stoves, of which thefollowing is'a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part of this specification, inexplaining its nature, in which Figure 1 is a longitudinal verticalsection of a stove having my improvement. Fig. 2 is a section on theline .90 m of Fig. 1. Fig. 3 is a horizontal section on the line y 3 ofFig. 1. Figs. 4 and 5 are views in perspective of the damper anddamper-rod removed from the stove.

The invention relates to that class of stoves havinga tank or reservoirfor heating water; and it consists in combining with the flue of thesection of the stove carrying the tank or reservoir and the oven orother equivalent flues of the other part of the stove two dampersarranged to open or entirely close openings from the down and up fluesof the stove into the flue-space about the tank or reservoir, so thatwhen the heat is caused to circulate about the oven of the stove or inany other portion of the stove there shall be no connection between thedownfiues of the stove and the flues about the tank or reservoir.

I have ascertained that if there is no damper for closing the openingbetween the space about the reservoir or tank and the uptake the draftof the stove is likely to be diminished, especially if the draft isnaturally weak; and this action upon the draft because of thisconstruction I account for in this way: The water in the tank orreservoir often becomes chilled or cold during the night or by theaddition of fresh water. This will chill the air in the chamber orpassage about the tank or reservoir, and this cool or chilled airescapes into the uptake, and if the draft is weak it will have aninfluence to disturb it and to check it, oftentimes to such an extent asto interfere with the baking, because the draft is only thrown down inthis manner in a cooking-stove-that is, down into the base portion ofthe stove-when it is desirable to cause the heat to circulate about theoven,

one or two sharp turns it is desirable that the draft be not interruptedby any means, and if cool air enters this draft, or if there is anopportunity for the air which has lost some of its heat not to take adirect course upward, then the circulation of the heat through the fluesand about the oven is imperfect.

Referring to the drawings, A represents the back plate of astovecontaining my invention. 0 is the downflue. E is the oven. F is theupflue; H is the reservoir or tank. I is the space about it; K, theopening in the back plate connecting the downflue with the space I. L isthe opening in the back plate connecting said space with the upflue. Mis the damper for closing the opening K; N, the damper for closing theopening L. I prefer that these dampers be arranged to swing respectivelyinto the down and up take passages, so that they not only uncover theopenings into the space about the tank or reservoir, but they alsopartially close the down and up flues below said openings.

I prefer to shape the back plate about the openings so that thedamperswhen closing said holes shall rest by gravity upon the plate.This I accomplish by forming recesses a in the front surface of the saidplate, which extend inwardly therefrom, and which have the inclinedledge a-that is, the recesses are deeper at the top than at the bottom.Each damper has the projecting portion a, which shuts into the spacebounded by the ledge, and also a flange, a which shuts upon the ledge a,and the bottom portion of said recesses are open to allow the dampers tohe slipped up into place from the back side of the plate. The pivot-barto which the dampers are attached has suitable bearings upon the backside of the plate.

It will thus be seen that the dampers when closed are a little inclinedfrom a vertical position and rest upon the ledges about the openings,and that when open they pass avertical line and are more inclined uponthe opposite side thereof.

I am aware that it is common to use one damper to close the openingbetween the downflue and the tank or reservoir space; but in stoveshaving a poor draft this does not seem and as this passage at the baseis long andhas I to be sufiicient to prevent the escape of the chilledair from the space about the reservoir or tank into the uptake-passage,and thereby stopping the draft or making it irregular.

The advantages of this invention have already been stated.

It will be seen that by shaping the damp erseat and damper as described,in closing the openings K in the damper-plate, they are held in place bygravity, and that theconstruction is cheap, simple, and desirable.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1. In a stove having a waterreservoir or tank surrounded by a flue or space, I, the combination ofthe flue-plate A, separating the down and up take flues O F from saidspace I,

the two openings Ktherein, one of which connects the downflue and theother the upflue with the space I, each of which openings is surroundedby the inclined ledge a, with the hinged dampers M N, each of which hasthe projecting edge or flange a, which rests upon the ledge a when theopenings are closed by the dampers, all substantially as and for thepurposes described.

2. The combination of the plate A, having the recesses a, the walls ofwhich support a rod or bar carrying the dampers M N, with said rod orbar, all substantially as and for the purposes described.
